Madonna's much-anticipated appearance at the Eurovision Song Contest in Israel has drawn a mixed response from viewers.
The star sported a black cape and eyepatch during her performance of 1989 hit Like A Prayer and new single Future, featuring US rapper Quavo.
Madonna defied calls from activists to cancel her appearance in Tel Aviv.
But organisers said the inclusion of Israeli and Palestinian flags in the show was not approved in advance.
Two of her dancers - each wearing a respective flag - walked arm in arm.

"In the live broadcast... two of Madonna's dancers briefly displayed the Israeli and Palestinian flags on the back of their outfits," a statement from the organisers said following the contest.
"This element of the performance was not part of the rehearsals which had been cleared," it added. "The Eurovision Song Contest is a non-political event and Madonna had been made aware of this."
While some criticised her decision to make a statement, others praised her for using her large platform to make a point.
As well as being off-key and a poor performer, Madonna managed to violate the EBU’s principle of non-political engagement by adding the Israeli and Palestinian flags to the back of two dancers backs. What a waste of money she was #Eurovision2019 https://t.co/jCsK1YcUq8— Luke Baker (@BakerLuke) May 18, 2019
#Madonna may have sounded flat but she won my heart tonight - being an artist is not always about having a perfect voice, but having something inspiring to say, and knowing how to deliver the message. She did outperform everyone else and she was #ArealQueen. #MadonnaEurovision pic.twitter.com/GE6Axyr6XX— Rosa Martinez (@RosaMartinezUK) May 18, 2019
Back to the music, and Capital Breakfast presenter Roman Kemp was unequivocal in his review, calling for her to be autotuned.
Some echoed his call for audio assistance:
Autotune! WELCOME!— India Knight (@indiaknight) May 18, 2019
She can't even do autotune right, what the hell Madonna #Eurovision— Eter Puralis (@EterPuralis) May 18, 2019
But others were full of praise for the star:
why did no one tell me Madonna is amazing! #Eurovision— 🌸 jar jar twinks 🌸 (@basicbisson) May 18, 2019
And finally, Danish actor Pilou Asbaek, who plays Euron Greyjoy in Game of Thrones, felt that Madonna's unusual outfit would be at home in the hit series.
If only it wasn't drawing to a close...
